CO₂ gas adsorbs on charcoal following Freundlich adsorption isotherm. For a given amount of charcoal, the mass of CO₂ adsorbed becomes 64 times when the pressure of CO₂ is doubled. The value of n in the Freundlich isotherm equation is _______ * 10⁻². (Round off to the Nearest integer)

(x/m) = k (p)¹/? (1)
64 (x/m) = k (2p)¹/? (2)
From equation (1) and (2)
64 = 2¹/?
2? = 2¹/?
1/n = 6
n = 1/6
⇒ n = 0.167
= 16.7 * 10? ²
